.WEDGE.

SPECIFICATION forming part of Letters Patent N 0. 715,786, dated December 16, 1902. Application filed March 19,1902- Serial No. 99,003. (No model- To all whom it may concern.-

Be it known that I, CHRISTOPHER J 0s. GRELLNER, a citizen of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Wedges; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to Wedges, and has for its object to provide a device of this class which is particularly adapted to be used in connection with shoe-handles or Wherever wedges can be used.

A further object of my invention is to provide a Wedge which will under all circumstances and conditions be held fast or holds itself fast, and therefore cannot come out accidentally after being locked or being once driven home.

A further object of my invention is to provide a wedge which is so constructed that it is cheap to manufacture and composed of a minimum number of parts.

With all these objects in view my invention consists in the novel arrangements of my wedge. i

The invention also consists in certain other novel features and in the combination of parts, which will be hereinafter fully described and afterward specifically pointed out in the appended claims.

Referring to the accompanying drawings, Figure 1 is a perspective view of my staple. Figs. 2, 3, and 4 are perspective views of my forms of wedges. Figs. 5, 6, and 7 show my Wedges in operative position. Fig. 8 is the same as Fig. 7 without the locking-staple. Fig. 9 is a perspective showing Wedge applied to a hoe. Fig. 10 is a side elevation of part of hoe shank, showing wedge prongs curved upwardly and downwardly. Fig.11 is a top plan of part of hoe-shank, showing wedge-prongs curved laterally. Fig. 12 is a fragmentary view of hoe-handle socket.

Like numerals of reference indicate the same parts through the several figures, in which- A is my staple having edge ends B beveled on the inner sides thereof. 1

C, D, and E indicate my wedges of different shapes. The end of wedges C is beveled on both sides at F and is provided at its top with a transverse groove or saddle G on the top J, being downwardly beveled on both sides at H equal in depth to the cross-section of staple A.

In operation the wedge O is driven into the wood, and the staple A is placed in position, the prongs of the staple straddling the wedge on either side of the transverse groove G. Said staple is then driven home, and as it enters the wood the prongs diverge by reason of the bevels on the inner sides thereof and the bevels H of the groove-saddle G, and the staple is driven until the top of the same sets snugly in the transverse groove or saddle G, thus making staple flush with wedge.

Wedge D is formed in the shape of an S, (see Figs. 7 and 8,) and the lower portion thereof is cut into three or more divisions, the

incisions extending about half-way up the wedge. The central division I is beveled on both sides, while the end divisions K and L are beveled on opposite sides and slightly bent and also on the inner sides at K and L.

Said wedge may or may not-be provided with the transverse groove G in the top thereof, as said wedge will hold without the staple A, although I Wish to reserve the right to use said staple, if preferred, and illustrate the wedge with and without the staple A, as in Figs. 7 and 8.

In operation the wedge E is driven into the wood, the central division entering straight and guiding the wedge. The end divisions, by reason of their opposite bevels and the bevels on their inner sides and the slight bend of the prongs, turn obliquely outwardly as the wedge is driven home, and, as aforesaid, the staple A may be used, if desired, as wherever the Wedges are formed with the beveled prongs the staple may be dispensed with.

Wedge E is formed with two prongs N and O, beveled on opposite sides and also on their inner side, the metal between the two prongs being cut away,as shown, the remaining metal being beveled on both sides, forming a knifeedge M, so as to split the wood fiber.

In operation the wedge is driven into the wood, and theprongs N and O, on account of the bevels and slight bend, turn obliquely in opposite directions as the wedge is driven home. (See Fig. 6.) The staple A may also, if desired, be used in connection with the wedge E.

Figs. 9, 10, 11, and 12 show my wedge applied to an implement \V, having a shank X. Y represents the handle-socket, having a pointed bottom Z for the purpose of guiding the wedge-prongs and of facilitating the bending or curling of the same.

Having thus described my invention, I do not wish to be understood as limiting myself to the exact construction as herein set forth, as various slight changes might be made therein by those skilled in the art which would fall within the limit and scope of my invention, and I consider myself entitled to all such changes.

Vhat I claim as new, and desire to secure by Letters Patent of the United States, is

1. As an article of manufacture a wedge having its lower'portion formed into two or more divisions, one of said divisions being beveled on both sides, the remaining divisions being beveled on opposite sides, all of said divisions being integral, substantially as described.

2. As an article of manufacture a wedge having the central lower portion thereof cut away, and the remaining material above said cut-away portion beveled on both sides, the material of either side of said cut-away portion forming prongs which are beveled on opposite sides substantially as described.

3. As an article of manufacture a Wedge formed substantially like an S the lower portion of which is formed into divisions, the central division being beveled on both sides, while the end divisions are beveled on opposite sides, substantially as described.

4. The combination of a wedge, having the lower portion thereof formed into divisions,

the central division being beveled on both sides, the end divisions being beveled on opposite sides, said wedge being provided with a transverse groove in the top thereof, and the staple having its prongs beveled on their inner sides, and adapted to straddle said wedge and register with the transverse groove in the top thereof, substantially as described.

5. The combination of a Wedge having the central lower portion cut away, and the remaining material above said cut-away portion, being beveled on both sides, the material of either side of said cut-away portion, forming prongs beveled on opposite sides, and slightly bent, said wedge being provided with a transverse groove in the top thereof and a staple having its prongs beveled on their inner sides, adapted to straddle said wedge and register with the transverse groove in the top thereof, substantially as described,and for the purpose set forth.

6. As an article of manufacture a wedge having the lower portion thereof formed into prongs, said prongs being beveled on opposite sides and slightly bent, and on their inner sides whereby said prongs when driven home turn outwardly and obliquely in opposite directions, substantially as described.

7. A wedge for tool or implement shanks provided with prongs oppositely beveled and beveled in their inner sides whereby said prongs will bend and curl outwardly and ob liquely while being driven into the tool or implement handle.

In testimony whereof I affix my signature in presence of two Witnesses.

CHRISTOPHER JOS. GRELLNER.
